Title: Magnetic recording medium
Inventor: YAMASHITA KUMIKO
IPC: G11B5/702
Filed: 1994-09-19
Abstract: PURPOSE: To suppress the floating of a medium from a magnetic head and to improve the signal output by the improvement in the head touch by setting the void ratio of a magnetic layer represented by the specific surface area of the layer to 0.04cm<2> /g or more. CONSTITUTION: To quantize the proceeding degree of drying of a magnetic layer, the residual solvent amount in the layer is measured. The residual solvent amount is measured by using conventional known solvent extraction. For example, in the case of using paint containing solvent having slow drying velocity such as cyclohexane, the drying the proceeded until the residual solvent amount becomes 0.8μg/cm<2> or less, and hence the void ratio of the layer can be set to 0.40m<2> /g or more. In this case, the void ratio of the layer is measured by using conventional known BET method. It means that the higher the specific surface area of the layer measured by the method, the more the layer adsorbs nitrogen gas. It is increased to 0.40m<2> /g or more to make it possible to suppress the floating of a magnetic recording medium from the head.

Title: Machine tool
Inventor: KITAMURA AKIHIRO
IPC: B23Q1/01
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To restrain thermal deformation of a column by integrally molding a cooling medium penetrating passage in the shape of a through hole in a wall material of a column wall of the column of a machine tool main body by casting, and flowing a cooling medium to the cooling medium penetrating passage. SOLUTION: A coolant penetrating passage 9 is integrally molded in the shape of a through hole in a wall material of a column wall 8 by casting so as to pass through into the wall material of the column wall 8 to both side surfaces of the column wall 8. At time of working, a spindle rotates at a high speed. Heating is caused in the bearing part in a spindle head and the meshing part of gears by this high speed rotation. These heat is transmitted up to a column 3, so that the column 3 is easily thermally deformed. In this case, since a coolant flows in the coolant penetrating passage 9 on the inside of the column wall 8, this generating heat is absorbed to thus prevent deformation by heat of the column 3, thereby machines a work with high accuracy by a tool.

Title: Pilot-type relief valve
Inventor: SUZUKI MIKIO
IPC: F16K17/10
Filed: 1983-11-28
Abstract: PURPOSE:To suppress the imbalance of pressures at the both edges of a main spool due to the tapered surface by forming a variable throttle part in which the throttle area is varied according to the displacement of the main spool. CONSTITUTION:A pressure port 34 is opened onto a valve opening 33 at the position separated in the axial direction from an exhaust port 35. The both chambers of a main spool 36 communicate each other through an orifice 37. When the differential pressure between before and behined the orifice 37 overwhelms the springy force of a spring 39, the main spool 36 moves in slidable ways to open the tapered surface 33b. Therefore, a variable throttle part 40 in which the throttle area is increased by the tapered surface 33b and the main spool 36 as the displacement of the main spool 36 increases is formed.

Title: Prediction coder and decoder
Inventor: SUGIYAMA KENJI
IPC: H04N19/177
Filed: 1990-08-24
Abstract: PURPOSE:To reduce a coding data quantity by providing a means obtaining plural frame and field signals coded precedingly in the prediction coding skipping a frame or a field of a moving picture and a prediction means generating a prediction signal closest to a signal of a frame or a field being a prediction object from the plural signals to the coder and the decoder. CONSTITUTION:Squaring devices 31, 32 and block accumulators 33, 34 are acted similarly and a mean square value of three kinds of prediction residues is fed to a comparator 30. A changeover switch 35 is selected so that a prediction signal whose square error (mean square value) is minimum among the three prediction signals from the result of the comparator 30 and the signal is outputted via a prediction signal output terminal 36. When a picture is not moving based on the adaptive prediction in this way, since a same field as a predicted field is in existence at a preceding (2N) or a succeeding (N) field, the same field is selected in the still state, and complete prediction is implemented. When any movement exists, it is highly possible that an N- preceding field with a close time distance is used at a 1st stage. Proper prediction direction is changed at a preceding and a succeeding field in a 2nd stage.

Title: Improving method for margin of data read
Inventor: YAMASHITA AKIYOSHI
IPC: G11B20/10
Filed: 1986-09-22
Abstract: PURPOSE:To improve the margin of distortion of a permissible reproducing signal by recording a dummy pulse formed by the combination of long/short pulses prior to the data and discriminating the inversion of the phase of the demodulated dummy pulse so as to decide the short/long pulse. CONSTITUTION:In recording a data from a computer to a cassette tape via a cassette tape recorder, a long pulse corresponding to the block 2 is outputted 255 times, then a long/short combination pulse corresponding to the block 3 is outputted 16 times and a dummy block 1 is recorded. Succeedingly, a reader block 31 and an information data block 30 are recorded. In reading them, whether the phase of the pulse of the block 1 subjected to pulse width demodulation is positive or negative phase sequence is decided depending whether the duration time of a high level block 3 is longer or shorter than a prescribed time. In case of the positive phase, the long/short pulse is decided by the time from the pulse trailing edge to the leading edge and in case of the negative phase, it is decided by the time from the pulse leading edge to the trailing edge, thereby the data read margin is improved.

IPC: C23G1/10
Filed: 1988-09-09
Abstract: PURPOSE:To produce a colored metal having specified coloration, with the grain boundary clarified, and with the surface difficult to stain by pickling a metallic material such as a valve metal or its alloy, heat-treating the material to grow the grains, and then forming an oxide film. CONSTITUTION:The metallic material to be treated such as a valve metal of titanium, etc., or its alloy is oxidized to form an oxide film on the surface, and the material is colored. In the coloration of the metallic material, the material is pickled with hydrochloric acid, etc., prior to the formation of an oxide film. As a result, a hydride is formed on the material surface, and minute ruggednesses are also formed. The ruggednesses having 3-100mum a roughness are preferably formed by adjusting the pickling conditions. The material is then heat-treated at about 900-1300 deg.C in a high vacuum to grow the grains. The material is anodized to form an oxide film corresponding to the ruggednesses. By this method, abnormal or uneven coloration is not caused, specified coloration is obtained, the surface strength is increased, and the material is not stained by the touch of fingers, etc.
